STOV E-l'VlAT.

SPECIFICATION forming part of Letters Patent No. 768,899, dated August30, 1904. Application filed January 23, 1904. Serial No. 190,275. (NomodelJ Be it known that I, ZACHARY T. HALL, a citizen of the UnitedStates` residing at Ridley Park, in the county of Delaware, State ofPennsylvania, have invented a new and useful Improvement in Stove-Mats,of which the following is a specification.

My invention consists of an improvement in a lire or stove mat adaptedto be placed ou a stove, range, &c., and transmit heat to a vessel,food, &c., placed on the mat without scorching or burning the same, saidimprovement embodying pieces of metal, such as sheet-steel, andlireproof material, such as as- I5 betos, and novel means for connectingsaid pieces, as will be hereinafter set forth, and pointed out in theclaim.

Figures 1 and 2 represent plan views of opposite faces of a fire orstove mat embodying my invention. Fig. 3 represents a diametricalsection thereof, on an enlarged scale. Fig'. 4 represents a perspectiveview of a detached portion.

Similarletters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a plate of metal, such as steel,and B designates a sheet of asbestos or other non-com bustible orlireproof material, the same being placed together bach to back, so thatsuch plate and sheet appear on opposite sides of the mat as thedilfcrent faces thereof. ln order to connect said plate and sheet, thelatter boing of,

less diameter than the former, I employ the inwardly-extending lips C,which are punched out of the plate near its peripheral rim or edge andembrace the peripheral edge of the sheet B and are pressed against theface of the sheet Within said edge or rim, thus interlocking the plateand sheet entirely around the mat within the peripheral rim withoutseparate fastenings as such, so that said plate and sheet are preventedfrom spreading apart or bulging at theii` peripheries, while the latteris permitted to expand uniformly at its peripheral portion within saidrim, and thus the body of the plate is prevented from buckling, whilealso leavingr the face of the metal plate A comparatively Hat throughoutfrom center to the extreme peripheral edge, in which condition it willrest upon a stove, range, Sac., and be highly heated thereby, the heatbeing communicated to the asbestos sheet, which while being on top andof a heat-transmitting nature is iireproof and will not Scorch 5S orburn the contents of a vessel, article of food, &e., placed thereon.sired, the asbestos sheet may be below, and 5o rest upon the stove,range, Sac., producing similar results as above.

of construction shown without departingl from the general spirit of myinvention, and I do not, therefore, desire to be limited in each case tothe same.

Having thus described my invention, what l claim as new, and desire tosecure by Letters latent, is

A stove-mat comprising a plate of metal and a sheet of lireproofmaterial, said plate and sheet forming opposite faces of the mat, saidplate being provided with inwardly-extending lips punched therefrom nearits peripheral edge and adapted to embrace the peripheral edge of thesheet.
